The problem with electricity is that you can't easily store it. And the only way to do so at large scale will be converting it to molecules. That implies hydrogen.
As a result, green electricity just means a nearly infinite supply of green hydrogen at the same level of cost. That implies nearly free hydrogen for any purpose.
Economically, that all leads to the hydrogen car as the future. You avoid both the weaknesses of ICE cars and BEVs.
This adds up to: 0.750.90.6*0.95=38% efficiency.
With an electric battery car. Its about 75-80% efficiënt in the whole chain. That means you need twice as many wind turbines to run the same amount of vehicle miles. The math just doesnt hold up.
So unless we cannot produce enough batteries or cannot make the grid stronger. Which both are possibilities. Hydrogen cars will probably be a dream. At this point it just doesnt make sense.
You're reading too much pro-BEV propaganda. They're just spreading FUD and trying to stop people from realizing there are alternatives.
It is not FUD or propaganda to say that the fuel cell cars you can buy today (or in the next 10 years) are not even close to 100% efficient. Nor is their round trip efficiency better than BEV. Nor or either of those numbers likely to change over that period.
Meanwhile, no one is looking at compromise solutions. Something like a PHEV or even a plug-in FCEV would solve a lot of these complaints right away. There are ways around these issues even in the real world.
Finally, it's not like 10 years is that long in the car industry. If FCEVs end up matching BEVs in efficiency in 10 years, that's means we're pretty much at the verge of FCEVs taking over.
Now this is propaganda.
